Pull media fixes from Mauro Carvalho Chehab:
"A series of media updates/fixes for 4.17.
There are two important core fix patches in this series:
- A regression fix on Kernel 4.16 with causes it to not work with
some input devices that depend on media core
- A fix at compat32 bits with causes it to OOPS on overlay, and
affects the Kernels where the CVE-2017-13166 was backported
The remaining ones are other random fixes at the documentation and on
drivers.
The biggest part of this series is a set of 18 patches for the Intel
atomisp driver. Currently, it produces hundreds of warnings/errors on
sparse/smatch, causing me to sometimes ignore new warnings on other
drivers that are not so broken. This driver is on really poor state,
even for staging standards: it has several layers of abstraction on
it, and it supports two different hardware. Selecting between them
require to add a define (there isn't even a Kconfig option for such
purpose). Just on this smatch cleanup, I could easily get rid of 8
"do-nothing" files. So, I'm seriously considering its removal from
upstream, if I don't see any real work on addressing the problems
there along this year"

Commit 2d1d4c1e591f made loop_get_status() drop lo_ctx_mutex before
returning, but the loop_get_status_old(), loop_get_status64(), and
loop_get_status_compat() wrappers don't call loop_get_status() if the
passed argument is NULL. The callers expect that the lock is dropped, so
make sure we drop it in that case, too.

When multiple CPUs are related in one cpufreq policy, the first online
CPU will be chosen by default to handle cpufreq operations. Let's take
cpu0 and cpu1 as an example.
When cpu0 is offline, policy->cpu will be shifted to cpu1. cpu1's perf
capabilities should be initialized. Otherwise, perf capabilities are 0s
and speed change can not take effect.
This patch copies perf capabilities of the first online CPU to other
shared CPUs when policy shared type is CPUFREQ_SHARED_TYPE_ANY.

coreboot firmware
This patch adds generic device information to the DMI table of
the cros_ec_lpc driver, needed for Chromebooks/boxes using a
custom coreboot firmware.
The DMI info would not contain "Google_*" as BIOS version string,
instead the system vendor string would still be "GOOGLE", so this
seems to be a reasonable match for every Chromebook/box running
a custom firmware.

During setup, qdio takes control of the presented ccw device and replaces

During shutdown, qdio returns its ccw device back to control by the
upper-layer driver. But there is a remote chance that by the time where the
IRQ handler gets switched back, the interrupt for the preceding
ccw_device_{clear,halt} hasn't been presented yet.
Upper-layer drivers would then need to handle this IRQ - and since the IO
is issued with an intparm, it could very well be confused with whatever
intparm mechanism the driver uses itself (eg intparm == request address).
So when switching over the IRQ handler, also clear the intparm and have
upper-layer drivers deal with any such delayed interrupt as if it was
unsolicited.

Instead of using OF-specific APIs to fecth device properties, let's switch
to generic device properties API. This will allow us to use device
properties on legacy ChromeOS devices and get rid of platform data down
the road.

The way we are supposed to put controller to sleep and wake it up does not
depend on the platform, but rather on controller itself, so we want to get
rid of suspend mode in platform data (and eventually get rid of platform
data completely). Unfortunately some early chromebooks (the original Pixel,
Acer C720) were shipped with config that requires manually re-enabling
touch reporting in T9. We will sort it out, but in the meantime let's
switch to a simple DMI quirk.
We'll keep pdata->suspend_mode for now and remove it when we rework
chromeos-laptop driver.

The Windows Server 2016 iSCSI target doesn't work with the Linux kernel
initiator since the kernel started sending larger requests by default,
nor does it implement the block limits VPD page. Apply the sector limit
workaround for these targets.

Smatch marks skb->data as untrusted so it complains that there is a
potential overflow here:
drivers/scsi/cxgbi/cxgb4i/cxgb4i.c:2111 t4_uld_rx_handler()
error: buffer overflow 'cxgb4i_cplhandlers' 239 <= 255.
In this case, skb->data comes from the hardware or firmware so it's not
going to overflow unless there is a firmware bug.

Here is another use after free if we reset the card. The adpt_hba_reset()
function frees "pHba" on error.
